Still an excellent AM4 board, even if the price isn't what it used to be
I've been using this motherboard for quite a while now and it's continued to perform flawlessly. Setup was straightforward, stability has been excellent and it's handled everything I've asked of it without giving me any reason to think about replacing it. The board offers a strong feature set for AM4 systems with plenty of connectivity, good build quality and enough expansion options for the vast majority of gaming and productivity builds. It also happens to be one of the better looking AM4 motherboards in my opinion, especially for lighter themed builds. The only thing that surprised me when looking at it recently was the price. It seems noticeably more expensive than when I originally bought mine, which makes it a little harder to recommend at current prices than it was a few years ago. As with DDR4 memory, part of that comes down to the industry gradually moving away from AM4 and DDR4 production towards newer platforms and AI-focused hardware, which has made some older but still popular components hold their value far better than many people expected. Overall, it's been an excellent motherboard and I'd happily keep using it for years yet, although new builders should compare current pricing against entry-level AM5 options before committing to a fresh AM4 build.

Decent AM4 motherboard and Ryzen 5000 ready
It has been a while since my initial purchase and so far it has been decent motherboard. It's a nice looking motherboard, good for a white build with silver/metal accent. It is also Ryzen 5000 ready out of the box, the layout and components are definitely high quality. One thing to note is the logo does not light up as shown in the pictures, it's just a silver paint. Comes with decent amount of I/O USB port and the shield is integrated so a relatively easy installation. The only issue I have faced are the fan headers. There are only 3x Fan channel headers, one of which is right in the middle of the board next to a pump header/CPU. Very awkward placing and it should have been on the top, side or bottom. Another annoying thing is the max limit for the fan speed control, whereas it is locked and will run 100% at 75+ C. This is BIOS related but can be improved in future update. Newer Ryzen 5000 CPU can run up to 70-95C so It just means whenever the CPU temperature hits 75ish, it will ramp up all fans. This can not be changed in bios, it is a safety feature which sucks but would love to change the maximum limit higher to something like 85C instead. Ryzen 5800x or heavy OC would easily hit this temp, but for this build I am running a 5600x so not an issue provided you have decent cooling. I would love to see more ARGB headers since it only comes with one. There is hardly any white AM4 motherboards on the market and I was deciding between this or the B550 Gigabyte Vision D, but did not want to pay the extra £100 premium. As you can see, it matches well with the white theme so definitely worth considering!

Good motherboard , but read the manual first to avoid the gotcha
I was going to give 3 stars, but then I realised that the information was in the documentation, but who reads all that prior to purchase Spec is rather good ( from my perspective ) , AM4 cpu, with two full length M2 connectors, 6 sata , plenty of ports on the back panel, and two graphics card slots + others, and so on BUT ( always a but ) If you use the two M2 slots, you will lose 4 sata connectors as they share the same bus on the board. Effectively you lose 4 onboard sata connectors. Quick fix to purchase an add on card with sata connectors, issue resolved So , lesson is , read the online manual prior to purchase, and buried in there, it does tell you that you will lose 4 sata ports if you plug in two M2 devices At least it was a simple remedy

Faulty motherboard
I purchased this for a white build i did but... only one memory slot works i actually tried the same sockets with 4 sticks and the pc still wouldn't boot, so now I have to use one stick. I've even spoken to asus and they agreed the motherboard is faulty.

Very strong motherboard, could handle me fist fighting my graphics card (rx 580) into the case aswell as accidentally bending a pin on the audio connector.

Very Very GOOD AM4 platform
After 8 months of usage. I can say this is a solid motherboard for it's price, I bought it on sale of course. Stable memory ocing and PBO on my R5 5600x.It has thunderbolt support, bios flash back, 2.5gb lan usb 3.2gen2, all features which I am using without problems. Not having a wifi onboard is not really a feature I am missing out and to add extra100AED to have a mobo with onboard wifi is ridiculous for me. I am on lastest bios firmware and no problems whatsoever.

Rewelacyjna płyta
Świetna płyta, solidnie zrobiona, dobre sekcje zasilania. Radiatory na oba dyski m.2. Jeden slot pracuje w standardzie Gen4 z kc3000. Intuicyjny BIOS, oraz opcja fast boot znacznie przyśpieszająca rozruch. Z 5700x całość pracuje stabilnie i w normalnych temperaturach. Bardzo estetyczna maskownica. Dobra ilość portów i ich umiejscowienie. Możliwość wgrania BIOSU bezpośrednio z pendrive. Jednak ASUS robi porządne płyty, na moment uciekłem do konkurencji, ale po wielu problemach zwróciłem płytę i zakupiłem tą. Polecam

Estupenda, la que más me gusta.
Tiene toques blancos o plateados en los disipadores de las etapas de alimentación y los disipadores de los m.2 y el panel trasero blanco. PCIeX16 4.0 PCIeX16 3.0 2 m.2 Aura Sync y aRGB. Socket AM4. 4 bancos RAM 6 SATA El conector de alimentación de la CPU es tipo 8+4. Si no lo lleva tú fuente (solo el de 8) puedes comprar un cable adaptador. Y lo mejor, la BIOS es tipo Flashback, que la puedes actualizar o recuperar por un puerto USB especial incluso sin CPU puesta. Buen precio. Para mí, una de las mejores placas base. (No wifi, no BT)
